Abstract

To study a spin dependence of the electron energy states in tree dimensional cylindrical semiconductor dots we consider theoretically the spin-orbit interaction impact on the electron quantum confinement in the dots. We solve the problem for InAs quantum dot embedded into GaAs matrix with the effective one electronic band Hamiltonian, the energy and position dependent electron effective mass approximation, and the spin-dependent Ben Daniel-Duke boundary conditions. It has been found that the spin-dependent boundary conditions lead to a spin-splitting of the electron energy states with non zero angular momentum. The splitting is strongly dependent on the dot size and can gain an experimentally measurable value for relatively small quantum dots.
